perf hists browser: Do not exit on tab key with single event
TUI help states for multiple event sessions the TAB/UNTAB keys are used to switch events. For single event sessions (e.g., the default) the tab key currently causes the tui to exit. Change that to do nothing since there is not no second event to switch to.
