Cannot delete child route after deleting parent route

Thanks for making this proxy!

We are finding that deleting /x before deleting /x/y causes an error.

import requests
requests.post('http://localhost:8080/api/routes/x', json={'target': 'http://localhost:5000'})
requests.post('http://localhost:8080/api/routes/x/y', json={'target': 'http://localhost:5001'})
requests.delete('http://localhost:8080/api/routes/x')
requests.delete('http://localhost:8080/api/routes/x/y')

20:01:59.255 - error: [ConfigProxy] Error in handler for DELETE /api/routes/x/y:  TypeError: Cannot read property 'remove' of undefined

However, deleting /x/y before deleting /x works as expected.

import requests
requests.post('http://localhost:8080/api/routes/x', json={'target': 'http://localhost:5000'})
requests.post('http://localhost:8080/api/routes/x/y', json={'target': 'http://localhost:5001'})
requests.delete('http://localhost:8080/api/routes/x/y')
requests.delete('http://localhost:8080/api/routes/x')

Good catch! #93 should fix it, I think.
