[Album] Fix a bug causing 32-bit snap-to-album to fail.

This extends a workaround we have for fixing ImageJ display issues with multi-
channel images to also apply for multi-component images. I still have no idea
why this workaround is necessary, nor why it works.

[Display settings] Don't totally fail to load incomplete display settings.

In particular, if the nominal number of channels doesn't match the length of
the per-channel display settings (e.g. for histogram max or gamma), then we'll
just use the first channel's settings rather than throw an exception and
therefore fail to load the file.
