Description

Like reported in #17941 (for Geographic Coordinate Systems, "GEOGCS"), I've also found that the name of each Geocentric Coordinate System ("GEOCCS") imported in srs.db from GDAL *.csv EPSG support files by QgsCoordinateReferenceSystem::syncDb() in QGIS 2.18 and QgsCoordinateReferenceSystem::syncDatabase() in QGIS 3 (during postinstall, in Windows by crssync.exe) is wrongly set to "Imported from GDAL" instead of with its proper name.

The bug lies in https://github.com/qgis/QGIS/blob/release-2_18/src/core/qgscoordinatereferencesystem.cpp#L1810-L1812

QString name( OSRIsGeographic( crs ) ? OSRGetAttrValue( crs, "GEOGCS", 0 ) : OSRGetAttrValue( crs, "PROJCS", 0 ) );
      if ( name.isEmpty() )
        name = QObject::tr( "Imported from GDAL" );

I think we can easily fix it:

QString name( OSRIsGeographic( crs ) ? OSRGetAttrValue( crs, "GEOGCS", 0 ) : OSRGetAttrValue( crs, "PROJCS", 0 ) );
      if ( name.isEmpty() )
        name = ( OSRIsGeocentric( crs ) ? OSRGetAttrValue( crs, "GEOCCS", 0 ) : QObject::tr( "Imported from GDAL" ) );

Anyway, to fix the names of the GEOCCSs already in srs.db shipped with both QGIS 2.18 and QGIS 3 we'll need to properly update it and upload it in the repository.
