PROJ 6 failures in rdefra

[rsbivand]

I'm testing rgdal and its reverse dependencies with PROJ 6 and -DACCEPT_USE_OF_DEPRECATED_PROJ_API_H. The CRS offered by PROJ >= 6 are changing, so that even though rgdal is still using the proj_api.h interface (for a few more months), the underlying CRS parameters are changing. Since few are using PROJ 6 yet, you have some time to fix this as rgdal will be built with < PROJ 6 metadata files in most cases. However, PROJ 6 was released 1 March, so you'll need to adapt. I attach my check files:

Issue still present in PROJ 6.1.0

Hi @rsbivand! Thanks for reporting this. I have updated the tests to be compatible with changes introduced by PROJ6.
