Describe the bug
After using tns migrate for a project with Vue 2.2, nativescript-vue-template-compiler package is not updated - its still ~2.2

To Reproduce

$ tns create myApp --template [email protected]
$ cd myApp
$ tns migrate
# now check the project's package.json - `nativescript-vue-template-compiler` version is still 2.2, while it should be 2.3

Expected behavior
After migrate, the nativescript-vue-template-compiler package should be migrated. In case it is not installed in the project before calling tns migrate, the migrate command should not add it.

Additional context
WORKAROUND: npm i --save-dev nativescript-vue-template-compiler@~2.3
