Stop ChatHistory fire dialog from restarting the app process

onDeleteAllClicked routed ChatHistory clears to clearSelectedDuckAiChats but left
shouldRestartAfterClearing at its default true, so after a bounded chat-subset
clear the dialog still called killAndRestartProcess(). Set the flag to false on
that branch, mirroring onDeleteThisTabClicked.
