[iOS] Transaction falsely shown being created and submitted

[pacu]

I'm using v1.7.8

Locale: Spanish

Server Info:

Reproducing steps:

• send a transaction with a memo to an address.
• observe that is being created and submitted.
• the toast message pops on the bottom of the screen

expected:
the transaction is confirmed and shown on the transaction history
result:

the transaction never shows up. Balance is unaltered. funds were never spent and tx never sent.

bonus finding

I sent many transactions testing this out.
One did appears to be sent, since I synced the same wallet on another app and the outgoing tx does not have a memo at all.
