Add tests for remaining actions

[geoffrich]

Resolves #5

This adds tests for the remaining actions:

• lazyload
• longpress
• pannable
• preventTabClose
• shortcut

It also adds cleanup to the existing clickOutside tests -- the nodes created for the test were not being removed from the DOM and the action wasn't being destroyed.

Writing these tests discovered a bug where the shortcut action was not updating params. This PR fixes that bug as well.

I'll open a separate PR to fix these. Didn't realize they were build breaking.
