Fixes

When first time using the App, stop the user from accessing the main page if the user's email is used and the device UUID does not match.
If the user have been using the App with a duplicated email in previous version, a reset email page will prompt when navigating to the reward page instead of showing wrong password error. This is a workaround for #266
Fix that the upload host in developer options is not saved.
Fix that an error would occur if the user press the upload button when there is not a single record. The upload button will be disabled if the user has 0 data. The page also shows the total records now.
Remove min/max validation for Heart Failure data template. Fixes #263
Enlarge the take-photo buttons and improve styling by highlighting the confirm button. The buttons of add-record and delete-photo page/popovers are also unified to this style. Fixes #262
