what if the file is under /gdata/.search/foo/file.
In that case we will be refreshing /gdata/.search/foo, which is not what we
want.

why don't you make this refresh the parent dir for a file?

Alternatively, you could use GetPathForDriveSearchResult function to get file's
real path before you call this function.

Per off-line discussion, added a check in
GDataFileSystem::RequestDirectoryRefreshOnUIThread() to see if the resource ID
is present. This will prevent us handling the virtual search path.
