[FIX] web: magic commands in search domain

Before this commit, when we used a domain on many to many relational
fields, the `dataContext()` returned the context of the field, which
contained a command tuple.

This causes an error server side, when a domain [('id', 'in', [[6,
False, [3,4]]])] is provided to search available records to fill the x2m
field.

Now, it returns the `currentIds`, which correctly gives the id(s) of the
records.
