Test fails on recent Emacs version

[juergenhoetzel]

Emacs 26.1:

In end of data:
git-link.el:495:1:Warning: the following functions are not known to be
    defined: dired-file-name-at-point, magit-file-at-point, string-blank-p
emacs -Q --batch -L . -l ert -l git-link-test.el -f ert-run-tests-batch-and-exit
Args out of range: "", 1, nil

Changelog for Emacs > 25.1:

* lisp/url/url-parse.el (url-path-and-query): Do not artificially turn empty
path and query into nil path and query, respectively.

Dissecting empty path now returns "" instead of nil.

It would seem advisable to add more recent Emacs releases to the Travis test matrix?
Also the emacs-snapshot used is also outdated:

Setting environment variables from .travis.yml
$ export EMACS=emacs-snapshot
...
0.01s$ emacs --version
GNU Emacs 24.3.1

Indeed. I think I looked into this but only 24.X packages are available, even with updated sources.

Thanks though. I will see what I can do.
