Locator shows all types of occurrences when no prefix is given

When using Locator and typing "gitsubmit" in the QtCreator source code, I used to only get "gitsubmiteditor(widget)?.[ch]" (files).

With 17.0 Beta1, when I have "gitsubmiteditorwidget.cpp" openI get all types of actions, like showing a git log or recent files. The other interesting files are far away at the end of the list. While working, I needed to change a lot between these files and it was a pain.

I later discovered, it works correctly if I type the prefix "a ", but that was not necessary in former times.

Was that an intentional change?
