minor aesthetic style issues

[eseiker]

these issues occur in firefox

• when collapsed sidebar expands, 'My Profile' nav item height changes instantly. this can be addressed by .nav-sidebar .nav-link p { text-wrap-mode: nowrap; }
• in 'My Profile' page, if profile image's width become less than 220px or 140px, the profile icon becomes ellipse, not circle. removing height from the style would resolve the issue.
