## What is the current behavior?

Manual navigation in the react tests is very finnicky

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->

Improved react test navigation so it more consistently moves from page
to page if you're manually reviewing react tests. This was done mostly
by adding missing `ion-page` components, but also by adding an exact
match to the main component. They're still pretty shaky and not great,
but better than before.
