app: do not feed babl with empty color palette. 

Since commit 4cf38d784f, when loading an indexed image, we would first
initialize a palette with 0 colors, then set it to the right colors.
Babl outputs the following message when initializing to 0 colors:

> ../../src/babl/babl/babl-internal.h:214 babl_log()
>	attempt to create a palette with 0 colors. using default palette instead.

Let's only set the palette to Babl when it has colors.
