cache-tree.c: use bug() and BUG_if_bug()

Change "BUG" output originally added in a97e4075a1 (Keep
rename/rename conflicts of intermediate merges while doing recursive
merge, 2007-03-31), and later made to say it was a "BUG" in
19c6a4f836 (merge-recursive: do not return NULL only to cause
segfault, 2010-01-21) to use the new bug() function.

This gets the same job done with slightly less code, as we won't need
to prefix lines with "BUG: ". More importantly we'll now log the full
set of messages via trace2, before this we'd only log the one BUG()
invocation.

We don't replace the last "BUG()" invocation with "BUG_if_bug()", as
in this case we're sure that we called bug() earlier, so there's no
need to make it a conditional.

While we're at it let's replace "There" with "there" in the message,
i.e. not start a message with a capital letter, per the
CodingGuidelines.
