Fix not running tests

[anikaweinmann]

Some tests are not running because there are GRASS GIS data used which are not included in the test docker. The ECAD location have to be changed to the NC-modis_lst mapset in the tests. Additionally, the other tests have to be checked.

Note: the currently used test dataset offers:

• https://grass.osgeo.org/sampledata/north_carolina/nc_spm_08_micro.zip

  • raster: lsat7_2002_10, landuse96_28m, aspect, basin_50K, slope, elevation
  • vector:
    • point maps: elev_lid792_bepts, elev_lid792_randpts, elev_lidrural_mrpts, elev_lidrural_mrptsft, firestations, hospitals, poi_names_wake
    • line maps: boundary_county, elev_lid792_cont1m
    • polygon maps: geology, nc_state

• https://grass.osgeo.org/sampledata/north_carolina/nc_spm_mapset_modis2015_2016_lst.zip

  • raster map time series (MOD11B3.A2016DDD.h11v05.single_LST_Day_6km), also stored as STDRS
