Allow to pass special symbols like `=` to `path` without urlencode

[chegoryu]

If you have directory with = in name, for example //home/my/dir/a=b/c=d, you can't just use https://yt.cluster/name/navigation?path=//home/my/dir/a=b/c=d url because it will open https://yt.cluster/name/navigation?path=//home/my/dir/a.

You can avoid this with url encoding (and use https://yt.cluster/name/navigation?path=//home/my/dir/a%3Db/c%3Dd link) but it is very inconvenient, especially when you use the hive format (for SPYT) and copy the table paths from the app log.
