stringAppend segfaults on non-boxed string in MatchCaseInteractive2

Description
The meta/MatchCaseInteractive2 test case currently segfaults. This is because it calls stringAppend on line 150 in MatchCaseInteractive2_matchRecord.c, where the second argument _str is the string from the input argument to the matchRecord function. _str does not seem to be boxed though, which stringAppend assumes. This causes stringAppend to get a bad string length when doing MMC_STRLEN on it, which gives undefined behaviour (for me it tries to allocate a 3 GB result string).

This was fixed some time ago. I updated MatchCaseInteractive2 in r24143 and added it to the working tests.

Unsetting milestone since bootstrapping is already finished.
