Bug 1719319: Don't try to use the URLPreloader cache before it's fully initialized. r=mccr8
Anything accessed before that time won't benefit from caching, and having
entries inserted into the hashtable before the cache file is read may lead to
undefined behavior.
This bug shouldn't be exploitable, since it only affects file reads that
happen long before any untrusted code has a chance to run.
