Share links are often wrong

### Steps to reproduce
1. Start the android app
1. Create a new folder
1. Create a link to share it
1. Fiddle with link permissions (add a password, an expiration date...)

I'm not sure all these steps are required to reproduce, but that's the workflow I'm usually doing.

Also, my server is rather slow (I sometimes have timeout errors when doing some requests), maybe this bug might be triggered by some race condition.

### Expected behaviour
The automatically (or manually) copied link should work.

### Actual behaviour
The copied link is often wrong (i.e. it points to a valid share, but the password is not recognized, as if it pointed to an other shared folder)
Usually, I have to browse (with the Android app) once again to the folder (back button then select the folder) and copy the link again to copy the right link
