Fixed some stuff regarding usercard (#2100)

- split everything into 2 separate labels, so we won't have any issues with dank dpi (like pajlada had) and no resizing to minimum size is required (which was apparently broken on Windows xd)
- decided to remove line, which is rather not visible / very small and can't be seen anyway
- added nice unicode characters for follow and sub label
- removed unnecessary QLabel include (which I believe was also introduced by me by an accident)
