Clean up stack after script_get_backtrace (#7854)
script_get_backtrace() was leaving its return value on the stack, corrupting subsequent lua operations for functions that did not immediately return. This problem can specifically be observed in the case of multiple "groupcaps" entries, each of which provides the legacy "maxwear" property. These cause a backtrace and thus pollute the stack for the following lua_next() call.
