Show pre-receive error message in merge request widget

Closes gitlab-ee#10165

See merge request gitlab-org/gitlab-ce!25708

When a merge fails due to a locked file, no feedback was given to the
user as to why it failed if the user used the Merge button.  However, if
the push attempt happened directly in the Web UI, the pre-receive
message would be displayed.

To be consistent and to make it clear why a merge failed, we now include
the pre-receive error message in the merge request widget.

Closes https://gitlab.com/gitlab-org/gitlab-ee/issues/10165

In 11.8, we added a fix for the SearchFilesByContent RPC in gitaly to
send back the response in chunks. However, we kept in the old code path
for backwards compatibility. Now that the change is fully deployed, we
