Fix activating a found item with hash in URL inside search dialog.

Summary:
When searched item has '#' in its URL and is activated (by pressing enter)
it should be shown inside its folder. But instead only folder before '#'
is shown. This patch should fix the issue.

Test Plan:

1. create folder '#subfolder' and place a file in it
2. go inside this new folder and search for files (Ctrl+s) with Search Dialog
3. choose found file and press enter
