Updated torbrowser_version number is not enough to change firefox-android versionCode number
When a new Tor Browser version doesn't include any new firefox-android
commit, its versionCode number will not change, although
MOZ_BUILD_DATE is changing.
The reason is that the function
fenix/buildSrc/src/main/java/Config.kt is taking the date from
MOZ_BUILD_DATE and using the number of hours from December 28, 2014,
to generate a versionCode. However,
MOZ_BUILD_DATE is based on the
commit date, on which we add the Tor Browser version as seconds, so
when a new version doesn't change the
MOZ_BUILD_DATE will only be change by a few seconds, which is not
enough to make
generateFennecVersionCode update the versionCode.
To fix this we can add an empty firefox-android commit as a quick
workaround for this release, before finding a better way to handle
MOZ_BUILD_DATE for new releases.
