Check if note exists in Firebase before saving

[ksigWyatt]

User Story

As a developer I want to make sure that I don't save the same note twice , so that I don't have many duplicate notes in the database.

Acceptance Criteria

• Duplicate notes are identified
• Notes that have the same ID / Text are not allowed to be saved

Tasks

• Get logic working
• Test it

Easy enough...

Logic works but I'm trying to configure a Bool function that returns true if a note exists because I'll be calling it often. That just makes sense. So I'm making the estimate a little higher because of that.

also there's a couple other issues associated with the login action -- testing revealed that sometimes the login action isn't fully completed... that can be frustrating for some users. I think however that it's an issue of connectivity. Or a firebase issue.
