Can you clarify why we need this test? To me, it seems redundant with the other tests that read NetCDF grids with GMTDataArrayAccessor information loaded with the exception of the to_netcdf line, but that is xarray functionality rather than pygmt.

This test was based on xarray's similar test at https://github.com/pydata/xarray/blob/befd1b98bd84047d62307419a30bcda7a0727926/xarray/tests/test_backends.py#L3729-L3736. I agree that this doesn't increase test coverage and seems redundant, but I feel like we should still have an explicit unit test for load_dataarray here, rather than just testing it indirectly in other functions.

…gTools#1518) Patches missing code coverage of pygmt.load_dataarray function wrapped in GenericMappingTools#1439. Checks that a NetCDF grid can be read with GMTDataArrayAccessor information loaded, and that load_dataarray fails when the cache argument is used.
