Reliably terminate soffice when connect throws an exception

...in which case setUp has already started self.soffice, but tearDown will never
be called.

For example, <https://ci.libreoffice.org//job/lo_tb_master_linux_dbg/29836/> had
thrown a css.uno.RuntimeException (for reasons that remain unclear) during setUp
of test_tdf46885_crash_chart_multiple_empty_cells_selected, and an soffice ->
oosplash -> soffice.bin process duo apparently kept running, so that all the
later tests' setUp each spawned an soffice -> oosplash that noticed that another
soffice.bin was still running, so would quickly terminate again, so connect
would raise a (somewhat misleading) "soffice has stopped" exception:
