Faster integration tests

[azat]

Before

running 7 tests
test tests::integration ... ok
test tests::test_pane_click_focus ... ok
test tests::test_query_logs_view ... ok
test tests::test_settings_align_keeps_logs ... ok
test tests::test_table_logs_pane ... ok
test tests::test_panes ... ok
test tests::test_queries_view ... ok

test result: ok. 7 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out; finished in 43.43s

And sometimes we even had tests that took > 60 seconds

test tests::test_settings_align_keeps_logs has been running for over 60 seconds
test tests::test_table_logs_pane has been running for over 60 seconds

Now:

running 7 tests
test tests::integration ... ok
test tests::test_panes ... ok
test tests::test_query_logs_view ... ok
test tests::test_queries_view ... ok
test tests::test_pane_click_focus ... ok
test tests::test_settings_align_keeps_logs ... ok
test tests::test_table_logs_pane ... ok

test result: ok. 7 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out; finished in 13.01s
