Enable DROP VIEW from a folder, bugfix

[jepett0]

KIKIMR-21808
#8067

It turned out during view testing that a basic query like:

DROP VIEW `some_folder/view`;

produces an error:

Click me

Status: GENERIC_ERROR
Issues: 
<main>: Error: <main>: Error: Check failed: path: '/Root/dedicated/some_folder/view', error: path hasn't been resolved,   nearest resolved path: '/Root/dedicated' (id: [OwnerId: 72075186224037889, LocalPathId: 1]), code: 2003

Bug is caused by the wrong path splitting in drop view operations. Previously a path like:

/Root/some_database/some_folder/view

was split into:

• working dir: /Root/some_database
• name: some_folder/view

parts which is wrong by SchemeShard's standards. To fix it, I split the path into:

• working dir: /Root/some_database/some_folder
• name: view

parts.
