Collapse and speed up the menu tests

Each test needs to reset browser cache and login, it's overly complicated
to have simple tests do all of these things between each test.

Instead, perhaps it makes sense to group the tests into groups of menu
items, eliminating needless test setup/teardown by keeping the assertions
but removing tests.

Before:
 02:30      107 (tests)

After:
 01:08       12 (tests)
