Incorrect deployment target in iOS projects

[e2l3n]

Deployment target is incorrectly incremented to 8.0 on prepare phase for iOS projects. This happens when a plugin is added which not necessarily contains dynamic cocoa touch frameworks.

The following excerpt uses the Hello-Plugin.

TPOPOVMAC:scratch tpopov$ ../bin/tns create TestApp
Project TestApp was successfully created
TPOPOVMAC:scratch tpopov$ cd TestApp/
TPOPOVMAC:TestApp tpopov$ ../../bin/tns plugin add ~/Desktop/Hello/hello-plugin
