Fix saved objects

[w33ble]

Fixes #1625
Fixes #1624

This handles several important things

• In the savedObject list, clicking on the item brings you to edit mode instead of view mode
• When a savedObject's indexPattern is missing, it takes you to the savedObject editor
  • Uses raw ES queries so the savedObject can be removed
    • Previously, you'd be stuck in a loop asking you to define an index pattern
• RedirectWhenMissing now appends the missing param to the URL
• The savedObject editor looks for the missing param in the URL and shows an error message about it
  • Encourages you to delete the savedObject
• Saved Dashboard objects in BETA1 had an indexPattern when they shouldn't, this will ignore them
  • Will also remove the indexPattern when saving/updating
• Apps will now fatally error on an unmatched redirectWhenMissing condition instead of just clearing the session

There's also a tiny amount of code style fixes and debugging cleanup

Big thanks to @spenceralger on this one
