test(logging): stop the location assertion matching the clock

test_location_toggle asserted that ":42" -- a bare colon plus the record's
hardcoded lineno -- is absent from a line formatted with include_location=False.
But every formatted line starts with an HH:MM:SS.mmm timestamp, so ":42" also
matches the clock whenever the minute or the second is 42. The test fails for
roughly 3% of runs with nothing wrong:

  2026-08-22 08:05:42.274 - INFO - test.logger - hello
                     ^^^ matches ":42"

Assert on the whole "module.funcName:lineno" token the format string actually
emits ('%(module)s.%(funcName)s:%(lineno)d') instead of a fragment of it. That
cannot collide with a timestamp, and it checks the thing the test is named for.

Confirmed by formatting a record stamped 08:42:42 -- both minute and second
colliding: the old assertion fails, the new one passes.
