[FIX] web: failing onchanges should not prevent to save

This patch is related to 82adba4714d9b809aad835d0d77e6b6f9fde8ddc

With the above patch, it wasn't possible anymore to save if an onchange failed. This isn't the expected behavior.
Besides, $.when.apply($, defs) is rejected as soon as one def fails, without waiting other defs to be either resolved or rejected.

This new patch allows to save if onchange fails, and wait for onchanges sequentially.
[FIX] web: base.css: fixed width for input of file type under oe_avatar

Browsers add different width to input of file type, messing up the usability of the
product formview placing  a 'phantom' box in front of the options. Added a specific
css rule for this case.
