target: handle command 'target current' when no target is present

Is it possible to run OpenOCD without any target, for example to
only dump the rom-tables of an arm dap, or to perform low level
jtag operations.
But without any target created, the command 'target current'
causes OpenOCD to abruptly exit.

Handle in command 'target current' the case of no targets.
