[FIX] web,lunch: separate search panel domain

Before this commit, the SearchPanel widget was given a single unified domain coming
from the view/controller. The issue was that some modules injected additional leaves
in this domain and there was no way to remove them/separate them from the original
view/controller domain.

Now, another paramater (the `viewDomain`) is given to the SearchPanel, containing
the distinct domain related to the view. The Lunch module has been adapted to give
the `location` domain through this new key.

Note that some tests steps had to be inverted since the method retreiving the
domain of the view/controller is asynchronous (needed by Lunch to give time to the
model to be loaded). It mainly concerns the RPC order which does not matter in this
case.
