autotest: Detect ambiguous hostapd SSID references

LinuxRouter.get_ssid() will default to using the first instance of
hostapd that was configured, but this may not be desirable in those
rare cases where we configure multiple instances.  When a developer
makes an ambiguous reference, detect this and raise an error rather
than behaving in an unexpected way.

TEST=wifi_matfunc runs correctly with this change after the remaining
WiFiManager tests are migrated.
