Add a missing test for --no-pickaxe-regex. This has been an error ever
since before the -S or -G options were added, or since
7ae0b0cb65f (git-log (internal): more options., 2006-03-01).

The reason for adding this test is that Junio suggested in [1] in
response to a later test addition in this series that it might be good
to support --no-pickaxe-regex in combination with -G. This would allow
for fixed-string searching with -G, similr to grep's --fixed-strings

I agree that that would make sense if anyone would like to implement
it, but since it dies right now let's first add this test to assert
the existing long-standing behavior. We can always add support for
--[no-]pickaxe-regex in combination with -G at some later date.
