test: Fixes for running tests interactively.

* testing/examples/babel.org: Change spaces to dashes in  #+name
lines.

* testing/lisp/test-ob-exp.el (org-test-with-expanded-babel-code):
(ob-exp/evaluate-all-executables-in-order):
(ob-exp/exports-inline-code):
(ob-exp/exports-inline):
(ob-exp/exports-inline-code-double-eval):
(ob-exp/exports-inline-code-eval-code-once):

(ob-exp/export-from-a-temp-buffer):
(ob-export/export-with-results-before-block):
(ob-export/export-under-commented-headline):
* testing/lisp/test-ob-lob.el (test-ob-lob/export-lob-lines):
* testing/lisp/test-ob.el (test-org-babel/inline-src_blk-default-results-replace-line-1):
(test-org-babel/inline-src_blk-default-results-replace-line-2):
(test-org-babel/inline-src_blk-manual-results-replace):
(test-org-babel/inline-src_blk-results-scalar):
(test-org-babel/inline-src_blk-results-verbatim):
(test-org-babel/inline-src_blk-preceded-punct-preceded-by-point):
* testing/lisp/test-ox.el (test-org-export/export-scope):
Bind ‘org-babel-inline-result-wrap’ and/or ‘org-export-babel-evaluate’
so tests work when users have customized these variables.

* testing/lisp/test-ob-exp.el (ob-export/export-with-results-before-block):
Add ‘org-trim’ where an extra newline was creeping in.

* testing/lisp/test-ob-lob.el (test-ob-lob/call-with-header-arguments):
Neutralize org-babel-insert-result, which was stomping on the buffer
contents and disrupting the test

* testing/lisp/test-org-element.el (test-org-element/block-switches):
Replace (should (and ...)) with multiple (should ...).  This gives
more precise indications of what is wrong when a test fails.
(test-org-element/link-parser): Require org-docview.

* testing/lisp/test-org-timer.el (test-org-timer/other-timer-error):
Add the error type for ‘should-error’.

* testing/lisp/test-ox.el (test-org-export/set-title):
(test-org-export/handle-options):
(test-org-export/with-timestamps):
(test-org-export/comment-tree):
(test-org-export/handle-inlinetasks): Let
‘org-export-filter-body-functions’ and
‘org-export-filter-final-output-functions’ to nil where an empty
string is the expected result.  ‘org-export-filter-apply-functions’
treats an empty string as special, and changes it to nil.  This
creates test failures when the user has customized these variables.

* testing/org-test.el (org-test-with-temp-text): Let ‘org-mode-hook’
to nil.
(org-test-table-target-expect): Require ert since this function calls
some of its should* functions.
