While refactoring of code model and project system was introduced a performance regression in find item method.
Finding uses linear search of project item by method:
Should be replaced on direct search by map:
It seem it was typo (selecting wrong method in code completion list).
Impact on IDE:
- time of configuring by code model is increased in x10 (x100) times. Time depends on project size. So project with 10K files cannot be configured in reasonable time.
- time of matching item->CsmFile on file event handlers is increased especially in case group changing.

Log: fixed Bug #196587 performance regression in NativeProject.findFileItem().
fix is safe and correct.
we regressed in performance mistakenly using O(n2) algorithm instead of O(n)
