apps: assign android log files to proper variable

When processing Android logs, they need to be assigned to the
logSummary.androidlog variable instead of the logSummary.netlog
variable.  Updated tests to check the log lines are assigned to the
proper variable.

Note:  Also fixed a test that was properly detecting the file type, but
did not have enough data in the simple log under test to verify that the
subsections of a system log were properly assigned.

TEST=manually tested on Chrome OS, Brillo and Android logs
TEST=ran 'grunt test'
