Timber lint check does not consider formatting string using indexing for backreferences

Given code:

`Timber.d("setMeasuredDimension(%d, %1$d)", size);`
or
`Timber.d("setMeasuredDimension(%1$d, %1$d)", size);`

Actual result:
Lint warns about invalid argument count for formatting string
Lint outputs:

Actual result:
No lint warning with proper format string including backreferences

Start by locating the Timber lint check that validates formatting-string argument counts, then reproduce the issue with the two Java snippets in the report. The fix is done when indexed backreferences such as %1$d no longer produce false warnings while genuinely invalid argument counts still do.
