fix(bash): rework #1509 to recover from the preexec failure (#1729)

In GitHub #1509, we blocked the unintended preexec event caused by the
keybinding of Atuin.  However, with that fix, the preexec event for
the intended user command is still missing.  In this patch, we try to
manually run the preexec hook when we detected the unintended preexec
(which means the missing intended preexec).
