I am landing this CL on behalf of hanxi@. This CL is copied and pasted from
https://codereview.chromium.org/2373713003/

I have extended the unit test timeout because the WebApkInstaller tests seem to
have been timing out (This CL should not extend how long the test takes to run)

File chrome/browser/android/webapk/webapk_installer.cc (right):

https://codereview.chromium.org/2381023003/diff/1/chrome/browser/android/weba...
chrome/browser/android/webapk/webapk_installer.cc:427: downloader_.reset();
I removed this from the diff.

It looks like base::Callback does not like getting deleted while it is being run
