[FIX] base: prevent copying of contact tag partners

before this commit, on duplicating a contact tag
will duplicate the assigned partners also.

suppose if we have a partner A with tag B assigned,
and then we duplicate tag B and create new tag C,
the newly created tag is automatically getting
assigned to partner A.

after this commit, the copy is set to False for
partner_ids field in tag and then the partners
wont be copied on duplicating a tag
