Add a message to confirm that all data was synced

[aniri]

Update the forms screen to show the manual sync button in case not all data was synced or a text message if everything was synced.

• there is a small layout change to be made for the case when the manual sync button is shown
• a text message should be shown otherwise (currently nothing is displayed in this case)

The UI can be found here: https://www.figma.com/file/lww9lcabUpamTZg8zCExI8/MV-2.0-Prototype?node-id=0%3A1

The texts should be:

Manual sync needed case:

• info text ro: Unele răspunsuri sau note nu au fost sincronizate. Apasă butonul pentru a trimite răspunsurile din nou.

• button text ro: Sincronizează datele manual

• info text en: It appears that some of the answers or notes have not been synchronised. Tap the button below to send the answers again

• button text en: Synchronize data manually

Everything was synced:

• ro: Toate răspunsurile și notele au fost sincronizate cu succes.
• en: All the answers and notes were synchronized successfully.
