[BUG] Request review in fresh install

[jesmrec]

Installing the app from scratch, and adding an oC10 account, i realised that many requests are repeated somehow. This is the request flow after clicking the Login button:

I see there:

• 3 calls to capabilities
• 7 calls to avatar 😨
• 3 calls to app/list
• 4 PROPFIND to the root (2 required: one for the list, other for the quota)

etc...

in oCIS account is also visible, not so many request but also repeated:

this might be reviewed to get throttled in needed requests and no repeated stuff.
