Mitigate attachment/send upload issues

Browse source 
This PR attends to mitigate (not fix) #2644.
There seems to be an issue when uploading files either as attachment or
via send via the mobile (Android) client.

The binary data gets transfered correctly to Vaultwarden (Checked via
Wireshark), but the data is not parsed correctly for some reason.

Since the parsing is not done by Vaultwarden it self, i think we should
at least try to prevent saving the data and letting users think all
fine.

Further investigation is needed to actually fix this issue.
This is just a quick patch.
