Fixed a merge conflict with master

Thanks for the PR, most of the changes are not required in NS7 - the only piece we can bring back is the sample runner, however I have intentionally removed it, as it wasn't useful at all. With a recent refactor to use the entry.js file as the entry, any sample can be tested, just by changing the import in the entry.js file - without the need to restart the whole build process (much much faster).

The docs/contribution guide should be updated instead.

To get started with the repo:

1. clone the repository
2. cd nativescript-vue
3. yarn - to install dependencies
4. yarn dev - to build nativescript-vue and nativescript-vue-template-compiler in watch mode
5. cd samples
6. ns run <platform> --no-hmr (disabling hmr isn't necessary, but preferred most of the time)

To test a different/new sample:

1. edit entry.js and update the require('./<sample>') statement to require any of the samples in the app folder.

@rigor789 @brysem #751 only update the doc and should replace this one if you are ok with it.

Thanks for the PR, but closing this - as the removal was intentional and #751 addressed the missing documentation.
