Before this commit, the mock server "_mockDefaultGet" method was a bit
naive:
- it accepted any 'default_' field coming from the 'kwargs.context'
regardless of the existence of the field
- it accepted any value for these fields
Now the method is looks a bit more like its original server-side
counterpart:
- the context keys are added if they correspond to actual fields
- a pseudo validation removes many2one fields values not corresponding
to any record
