Fix setting of nodata in export2tiff pipeline, round 2

[mlubej]

ExportToTiff pipeline didn't behave as expected. When merging tiffs, I wanted to set the empty space to the no-data value, turns out there were issues because of:

• not setting the -init param
• not using the values as strings (- was understood as a parameter???)

Thanks @batic for the help.

is there a way to add a test for this?

One should be able to read metainfo from the raster and compare with the expected values for various combinations of parameters and parameter values.
