playerctld (https://github.com/altdesktop/playerctl/issues/161) is a proxy daemon for the currently active player by playerctl, which facilitates managing mpris players, forwarding requests to the currently active/last active player, and sorting out troubles with selecting the correct player manually.
Unfortunately, it also creates an annoying issue with kdeconnect: when playing media on the phone, kdeconnect publishes the state to the computer through the mprisremote plugin - then, playerctld picks it up as active player, and registers its own mpris media player. As a result, the mpriscontrol plugin sees this as a running media player, and in turn, publishes the state back to the phone, essentially creating another media session on the phone, resulting in two notifications. As playerctld is _always_ only a proxy to another media player (or kdeconnect), it can safely be ignored, just like kdeconnect itself already is. This commit adds an if check doing exactly that.
## Summary
This patch makes SMS message field scrollable and limits its height to ⅓
of window height (or ⅔ for smaller windows) so messages in conversation
are shown even when writing very long messages.
## Test Plan (and screenshots)

### Before:
Message field height was not limited. Message field could be even higher
than window. That makes first lines of this field and messages in
conversation inaccessible.
### After:
Message field height is limited to ⅓ or ⅔ of window height. When text
content reaches this threshold, scroll bars will show up.
SMS character counter was changing its width (both growing and
shrinking) so it also resized message field (and that caused text
reflow). This patch makes counter width only grow.
Type SMS that is long enough to make SMS character counter wider than
“Send” button. Remove the text (leave there 150 or 60 chars to keep it
visible). Character counter should keep its width.
