fix($http): don't covert 0 status codes to 404 for non-file protocols

PR #5547 introduced conversion of all 0 status codes to 404 for cases
where no response was recieved (previously this was done for the
file:// protocol only). But this mechanism is too eager and
masks legitimate cases where status 0 should be returned. This commits
reverts to the previous mechanism of handling 0 status code for the
file:// protocol (converting 0 to 404) while retaining the returned
status code 0 for all the protocols other than file://

chore(npm): clean up shrinkwrap file, remove unused properties

from our experiements it appears that the presense or absense of the from and resolved properties
makes no difference on the behavior of  but  updates these properties
with different values depending on different state of the cache and node_modules.

So in order to get clean diffs during updates, we are just going to drop these properties and have
a script to do this automatically.

Long term this should be fixed in npm: https://github.com/npm/npm/issues/3581
