[parser] Skipping inner funcs: fix related to aborting preparsing. When skipping inner funcs is enabled, we also track variables for top level funcs. Thus, we also declared the function name for the function scope, even though it was the function scope for a function whose preparsing was aborted. This lead into declaring the function name twice. The fix is to declare the function name only in the success case. The code was "wrong" before too, but this was never a problem, since variable tracking and aborting preparsing were enabled for disjoint sets of functions (aborting preparsing only for top-level, and variable tracking for non-top-level).
