Add MaterialSideProfile dark mode support

[beppino]

Tested on macOS 10.15.4.
Start application with system in dark mode and switch to light (with MaterialDarkModeToggle). The MaterialSideProfile is losing his layout.
Not if os is initially set to light mode; all seems remain consistent.

Can you show me the code i can't reproduce on my own.

Here's the code I used:

<ma:sideprofile.MaterialSideProfile url="https://miro.medium.com/max/5760/1*r2AuXvDuxdRWCqvmBhlssw.png">
                <m:MaterialImage url="https://res.cloudinary.com/teepublic/image/private/s--XqBcjwVK--/c_crop,x_10,y_10/c_fit,w_830/c_crop,g_north_west,h_1038,w_1038,x_-104,y_-105/l_upload:v1565806151:production:blanks:vdbwo35fw6qtflw9kezw/fl_layer_apply,g_north_west,x_-215,y_-216/b_rgb:bbb0e4/c_limit,f_jpg,h_630,q_90,w_630/v1548392518/production/designs/4075639_0.jpg  "/>
                <m:MaterialLabel text="GWT Material" textColor="WHITE"/>
                <m:MaterialLink text="[email protected]" activates="dropProfile" iconType="ARROW_DROP_DOWN" iconPosition="RIGHT" textColor="WHITE"/>
            </ma:sideprofile.MaterialSideProfile>
