Fix Profile/ProfileEdit ViewController

[ltsuda]

@chrisfsampaio need ideas ):

Now:

• User chooses an image from Library
• Upload to FirebaseStorage and get URL

1.0 User cancel on ProfileViewController, delete image from FirebaseStorage or User Account could fail and we could not cancel again. Only can go forward or open the app again 1.1 If user cancel on ProfileEditController, Profile's image was already changed in FirebaseStorage which is wrong

Need to fix:

• User chooses an image from Library
• Keep image 1.0 User cancel on ProfileViewController, go to CreateAccountViewController without uploading image 2.0 If user did not set an image when creating an account, ProfileEditController did not load because there's no image to download 2.1 If user cancel on ProfileEditController, go to SettingsTableViewController without saving any data to Firebase
• Try to save first/lastname, if succeed then try to upload and save image's profile

Fix 1: If user cancels registration, do not delete image from Firebase, only deletes account.

• 1.0 User cancel on ProfileViewController, go to CreateAccountViewController without uploading image

Fix 2.0: Add local image if user do not upload an image.

• 2.0 If user did not set an image when creating an account, ProfileEditController did not load because there's no image to download
