In BA plugin, error with type checking of get/release resource behavior actions

[Etienne13]

Summary

When using a get/release resource behavior action (noted <! and >!), the plugin fails and produces the following error message:

type error for 'lock', 'subprogram classifier' expected, found 'requires data access'.

This is a recent regression.

Steps to Reproduce

1. import the following model
2. see the error message attached to the behavior actions (no error message should appear since the model is correct)

package issueGetReleaseResource
public
	
data d
end d;

subprogram spg
  features
	lock: requires data access d {Concurrency_Control_Protocol => Protected_Access;};
  annex behavior_specification {**
	STATES
		singleton: initial final state;
	TRANSITIONS
  		t: singleton -[]-> singleton
   		{
   			lock!<;
   			lock!>
  		};
**};
end spg;
	
end issueGetReleaseResource;
