[UI] Pagination works strange in case if there are a lot of packages from different tenants

[Anastasia Kuznetsova]

Steps to reproduce:
1. Import N packages from different tenants (more than 20)
2. Log in Web UI as admin user
3. Navigate to "Murano" > "Manage" > "Package Definitions"
4. Import M packages
5. Check work of pagination

Observed result:
Pagination works really strange on the first page user see the list of his own packages and packages uploaded by users from other tenants (list 1). On the second page user see left part of his packages (list 2) and he can only go to the previous page. After clicking on "Prev", user get new list of packages, that is not equal to list 1 and he can navigate _one_more time to previous page.

    Remove owner filter from Package Definitions page

    This patch deletes owner filter which breaks pagination and leads to
    the impossibility to add filter by package name
