Imagemagick settings are not taken into account

Problem/Motivation

I use this module in combination with imagemagick. In imagemagick there are settings, in particular the color profile setting, which are not taken into account in combination with imageapi_optimize. The color profiles are lost even if I don't add any processors to the pipeline. Disabling the pipeline of an image style fixes this issue.

Steps to reproduce

• Add an empty pipeline and set it as default
• Install and set imagemagick as the image toolkit (/admin/config/media/image-toolkit)
• Under Advanced image settings Set Convert colorspace to sRGB
• Upload an image with a inappropriate color profile for the web (Eg. Adobe RGB)
• Render an image style of it.

To see the correct result without imageapi_optimize:

• Delete the pipeline
• Now the color profile of the image style should be correct.
