[Typescript Angular] The typescript interface method names does not match client generated names for "Form"

[RodolpheNivelet]

Since this PR #671 , the interfaces generated by angular-typescript are wrong for those "Form" type endpoints.| They are lacking the "Form" suffix.

ex: In api.service.ts: myPostEndpointForm(...) In api.serviceInterface.ts myPostEndpoint(...)

I will produce a PR to erase this issue.
