[ZEPPELIN-1864] Improvement to show folder and note after searching note
### What is this PR for?
This PR is for improvement to show folder and note after using the filter.
And I found some bugs and fixed like this.
the following list is improvement and bug fixed.
1. After using the filter in Zeppelin Home, every note is shown by the form
[FolderName/NoteName] like below. It would be nice to show folder icon and note
icon as previous status.

2. When using the filter, some functions and icons next to note and folder
are disappeared.

3. When using the filter, the `Rename Note` function doesn't work. ( When I
was handling this PR, this bug was discovered.)
