Small correction (as spotted by Aaron off-list): In `AddVM` in the same
file [1], we also have a line

22        me.extraRequestParams.poolid = me.pool;

This one does not break any edit windows, because the
`extraRequestParams` object is created a few lines above that in the
`Ext.define`, so it is not shared between all `Proxmox.window.Edit`
instances:

9      extraRequestParams: {
10         'allow-move': 1,
11     },

... but if I understand correctly, it *is* shared between all `AddVM`
instances. Again, I think this shouldn't break anything because we reset
`poolid` every time `initComponent` is called, but the pattern is
somewhat error-prone. It might be better to change line 22 to:

22        me.extraRequestParams = { 'allow-move': 1, 'poolid': me.pool };

... and remove lines 9-11, to always create a new object in
`initComponent`. What do you think?
