Problem in `tm_raster()` for stars objects.

[olivroy]

I added a tryCatch() condition back in September, but it seems that with data.table 1.15, the warning has intensified. https://github.com/r-tmap/tmap/commit/93d2d9407353a86f4e22005e39f649f6328bc583

I think we should not ignore this warning as it will not be very safe against future versions of data.table.
