update to Chrome 74

- the CL https://chromium-review.googlesource.com/c/chromium/src/+/952522
  introduced a security check which makes it necessary to access the
  chrome containers with IP addresses.
  The --hosts parameter resolves the given hosts and constructs URLs.

fixed a few silly bugs concerning the parameter handling
