tests: fix window switch tests (#581)

lread · web-flow · commit 18124a33467d · 2024-05-15T12:52:52.000-04:00
Safaridriver is not great with mouse clicks, press enter on link to create new target window instead. - `test-switch-window` - assert window count earlier for clearer failures - `test-switch-window-next` - was using unrealized `repeat`s so was effectively testing nothing. Reviewed and rewrote with some compensations for our odd little safaridriver. Closes #579
