There are a few bugs with completion-pcm-try-completion not returning
text whose case matches the completions, even when the case is identical
between all the completions.  I added some tests covering them.

Ultimately, these bugs are nicely fixed by an improvement to
Ftry_completion; the removed conditional (and its associated comment) in
Ftry_completion didn't actually improve behavior, but instead made case
behavior worse.  I believe the bad behavior which this conditional was
originally attempting to stop was removed at some point by other
enhancements to Ftry_completion's completion-ignore-case behavior, so
the conditional isn't necessary anymore.
