updates adb helper to cope with no space after word device

adb seems to have changed its output from
"emulator-5554 device " to
"emulator-5554 device"
note the space after the work device

change uses a regular expression to match the word device with or
without a space after it, but does not match the word devices
also takes into account that there is a space after the word device
for a physical device, such as
"192.168.56.101:5555 device product:vbox86p model:device1 device:vbox86p"
