Make sure that m_selectionToggle is not 0 before calling deleteLater()

Commit 1938ad54d4ee640f04d24bad3b690095bc9b8668 replaced delete by
deleteLater(). However, the latter cannot be used safely with null
pointers. This commit adds a safety check in order to make sure that
we do not get a crash.

Thanks to Christoph Feck for pointing out this issue.
