Git doesn't track renaming if a file has too much changes. The change renames
.html files to .js files. This change must be submitted together with es6
modules conversion.
The build and tests fail on this change - this is expected and must be
overwritten manually.
This change was produced automatically by ./es6-modules-converter.sh script.
No manual changes were made.
