When executor passes the instruction to loopback methods,
loopback modifies the data. Since we are loading the data using
`require` such changes affects also code that calls
`require` for one of the instructions files.
This change adds a deep clone step to prevent this issue.
Split bootLoopBackApp into two steps:
- compile
- execute
Most of the changes are just shuffling the existing code around.
What has changed:
- `loopback.autoAttach()` is called after `models/*` are required.
The calls were made in the opposite order before this commit.
