ui: avoid panic when terminal window is shrunk
When using a tiling window manager, aerc terminal dimensions may be
greatly reduced after a new window has been created by :open. When the
ui attempts to render to formerly-valid coordinates, SetCell & Printf
may panic. Replace panic() with no-op in both functions to prevent
aerc from crashing after a window shrink.
