Fix "Cannot read property of null/undefined".
Added longer timeout for http_client

To compensate for slower boot time of Android VMs and for network issues, wait longer before timing out (but only at startup).
Added fix to remove app/apk files from zipPath before appium starts to unzip them. If this is *.app located in Payload folder then folder is being removed too. Fix is done because fruitstrap sometimes failes to install app file on the device when /var/folders/... are not cleared correctly.
