Fix logic in project's file insertion 

The function "file_search" in core.init was sometimes giving a wrong index
value, off by one.

The problem happened for example when the entry to search was "less than"
the first entry, the function returned a value of two instead of one as
expected.

The bug was easily observed creating a new directory with a name that comes
as the first in alphabetical order within the project.
