travis.yml needs to be adjusted

Thanks for the work @OanaIlea.

I still get a 'Schema incomplete' in admin/reports/status.

@jcnventura: How did you apply the patch? I tried the latest one and with the patch utility I got and error when it tried to rename an existing config file:

$ patch < ../../../portuguese_configs.patch 
patching file .travis.yml
patching file search_api_solr.solr_field_type.text_pt-br_7_0_0.yml
Cannot rename file without two valid file names
17 out of 17 hunks ignored
patching file search_api_solr.install

I'm renaming it manually now and test it.

Ok, that did not work as intended as some of the changes were still missing.
What seems to work is having composer apply the patch during module install (via the cweagans/composer-patches plugin).

@jcnventura and I checked his project code and the patch had been applied correctly and the field type was visible in the GUI. It looks like there is a second part to this issue that is not fixed yet.

The issue that remained (#3091574) should be fixed now.
@jcnventura: Please feel free to reopen if it still does not work.

Yes. This, in conjunction with the other patch seems to work just fine!

Thanks!
