Fix for #7374 project prefs path breaking project open.

This fixes the bug in two ways:

* globmatch no longer uses the "matchBase" flag for directories
* the current editing file is set to the new project directory *after* the project
  scoped preferences is changed

Either one individually would fix it, but both prevent potential other problems.
Fix several issues raised in #7149:
* When search scope is a single file, skip exclusion filter entirely
* If exclusions filter results in 0 files to search, show a message to that
effect and leave search bar open so user can adjust filter
* When editing a filter, show how many files are still included out of the
total number of files in the current search scope

Also cleans up FindInFiles to centralize the filtering code more, and
simplify _doSearchInOneFile() & its call sites.
