Fixed absolute path calculation for workspace resources

* Previously it was assumed that projects are physically stored below the workspace directory. When projects are located e.g. in a git repository and imported into the workspace this assumption does not hold. This was fixed with a proper lookup. * Changed API of the convertToAbsolutePath method to take a string instead of a file, since all callers had to create a file from a string anyway.
