Merge branch 'fix-code-preview' into 'master'

 Fix code preview theme setting for comments, issues, merge requests, and snippets

User color scheme was not being used: default white color scheme was always chosen. Also, default background for code in notes was always overriding the user color scheme.

Closes #1139

See merge request !357
