Macro-recording fails for H_Watershed when exporting mask

[walkernoreen]

When running H_watershed & exporting the region mask, the macro is not recorded properly. (For exporting label image it does work well. Also for interactive H_watershed it does work correctly).

To reproduce the issue:

• open Blobs sample image
• run H_watershed with “export regions mask” checked and otherwise any values.
• the recorded line will lack the parameters: run("H_Watershed");
