This commit reduces the size of the icons used for the employee presence
status.
Prior to this commit, these icons were using a rule to define if they
should be diplayed in large or not, by checking the html tag of the
element they are in.
These icons were also styled with custom CSS to adjust their size, while
classes like `fa-lg` could eventually provide a workaround.
This approach was causing issues especially in kanban cards, were these
icons would appear massive and cause visual cluttering.
To improve the render of these inside cards, we simply remove the
custom styling applied to these icons.
