[Enhancement] Improving background tasks

[g123k]

Hi everyone,

We get many complaints from users who don't understand why the application is acting weirdly. Very often, the root cause is a long list of background tasks that hasn't been able to run.

1. Try to send the request immediately with a short timeout
2. If this doesn't work, transform it into a background task.

Some examples of "simple" fields: update country, website…
