[FIX] mail, crm: do not display body in creation message when having a subtype

Right now on few business objects (like leads, invoices, tasks, helpdesk
tickets etc) creation message contains
  * subtype description;
  * generic creation message;

This looks like multiple creation message on chatter after creation of the
record as you generally have "Task Created - Task created" (subtype description
then generic message).

This happens when we provide custom subtype on creation by by overriding
`_creation_subtype` method.

This commit fixes the issue by only using provided creation subtype and
removing default body. If creation subtype is not provided default creation
message is posted as before.

In this commit we also fix subtype for Lead/Opportunity creation and make
it generic ('Lead/Opportunity created') to avoid inconsistent behavior.

Finally some cleaning is made in method naming. Semi followup of 92e9e84b63a266b39d556c1db1d336373dc8b303
