Fix acrylic brush flash/fade on new tab creation. (#1092)

Browse Source 
Fixes #1082 -- #853's fix of the acrylic background's flash/fade on any settings change managed to cause a flash/fade on new tab creation. This change removed both flash/fades. #853 split background brush initialization from background color changes; due to the brush being constructed with a default color and then the color being initialized later, new tabs were getting the flash/fade that accompanies a re-focused fluent-style acrylic background. This PR initializes the acrylic color at brush initialization to avoid the problem.
