UnreadNotice: Remove disused 'limited' property
UnreadNotice: Remove disused 'limited' property

Remove the disused 'limited' property from 'UnreadNotice'.
It was used to limit the display of unread messages to '99+'.

As this component is used in a single place, the 'Chat' component,
if we decide to change the behavior we can change it directly,
inline, in the 'UnreadNotice'.
