Always add braces to single-line if-statements

The Chromium/Google style guides does not enforce curly braces for
single-line if-statements, but does strongly recommend doing so. Adding
braces will improve code readability, by visually separating code
blocks. This will also prevent issues where accidental additions are
pushed to the "else"-clause instead of in the if-block.

This CL also updates the presubmit `eslint` to run the fix with the
correct configuration. It will now fix all issues it can fix.
