Do Not Insert In Progress Insertion

[seanparsons]

Problem:
When an insertion was in progress but not complete, tabbing away from the editor would result in a zero-sized element being inserted.

Cause:
The editor onBlur handler was clearing the interaction session, but applying any inflight changes which caused the element to be inserted.

Fix:
Now the interaction session is cancelled without applying changes and the editor mode is reset to select mode.

Commit Details:

• resetStateOnBlur now clears the interaction session without applying changes and resets the editor mode to select mode.

Manual Tests:
I hereby swear that:

• I opened a hydrogen project and it loaded
• I could navigate to various routes in Play mode
