[FIX] base: extrapolate table name on uninstall for ir_model_constraints 

When uninstalling a module, the model *may* be removed from the registry
before the removal of the model constraints; to prevent crashing in
those cases, a simple replace('.','_') on the model name should allow to
obtain the table name in these cases.
