Improve performance of bp_docs_get_current_doc()

Not really used in the rest of Docs, this makes it better at fetching the
intended Doc
When saving Doc, use bp_docs_get_current_doc() instead of relying on get_queried_object()

This ensures that the value is filterable

Remove switch case regarding the setting of a base URL
Fix logic in bp_docs_is_existing_doc()
Do access protection query at pre_get_posts:28

Firing at priority 10 was causing conflicts with other plugins using the
pre_get_posts hook. Due to a limitation in WP's filter API, calling
remove_filter( $hook ) while in the process of doing $hook will cause other
items hooked to $hook to be removed when those other callbacks are at hooked
at a priority directly adjacent to the original hook. See
https://core.trac.wordpress.org/ticket/17817 for more background on the
limitations of nested remove_action() calls.

Props to @christianwach and @stephenharris for researching the conflict and
suggesting the solution.

Clean up groups_template global in bp_docs_doc_associated_group_markup()

On single doc pages, the pollution of the $groups_template global by this
function was causing the page to be rendered nearly infinitely on large sites,
because of the bp_has_groups() loop on groups/single/home.php template. By
keeping a backup of the global and replacing it when we're done, we ensure that
this looping does not happen
