• test_delete_document_and_revisions
• test_request_with_timeout_should_work
• test_can_load_entities_with_no_tracking
• test_can_run_spatial_queries_in_memory

Not passing:

• test_plain_revisions_subscriptions_compare_docs
• test_session_in_subscriptions_should_not_track_revisions
• test_will_call_on_before_delete_when_calling_delete_by_id
• test_wait_for_indexes_after_save_changes_can_exit_when_throw_on_timeout_is_false
• test_can_use_on_session_disposing_event
• test_request_timeout_should_work
• test_search_with_highlight

All of the tests that don't pass have comments with either exceptions they throw, or short explanations of what went wrong.

Other tests that are in the ticket, but not in this pr, don't work because of either non functioning event listeners (addBeforeQueryListener and similar), or they lack exception types.

Let's remove the tests that don't pass yet from this PR. We'll include them in second phase. Mark them as unresolved on YouTrack issue @yh-0
