Fixes #7635 appointment comments double escaped (#7638)
* Fixes #7635 appointment comments double escaped
The day, month, and week appointments are showing html entities for
things like apostrophes, quotes, ampersands, etc because the data is
being double escaped. We need to make sure we only do a single version
escape on the calendar.
The calendar uses the pcVarPrepHTMLDisplay function to escape this and
other fields which then get double escaped when passed through OpenEMR's
attr function. We fix this issue by the removing the attr and relying
on the pcVarPrepHTMLDisplay. This makes it so if anyone is using the
PostCalendar/pnuserapi.php to grab events it will still work properly.
