The .uno:DBViewTables and .uno:DBViewQueries commands are executed
asynchronously by posting an event to the main thread from
OApplicationController. This creates a race condition for the test where
the following call to .uno:SelectAll silently fails if the event is not
processed before the command is dispatched. After that the attempt to
open a new subcomponent fails, the OnLoad event is never sent and the
test gets stuck in an infinite loop until the kill-wrapper kills it.
This happens for example in the following build log:
https://ci.libreoffice.org/job/gerrit_linux_clang_dbgutil/193243/console
I think I can artificially reproduce the problem locally by adding a
sleep in OApplicationController::OnSelectContainer and at least in that
case this patch appears to fix it. It just makes the tests wait until
the main thread is idle after issuing the commands to switch the view.
