filter tool doesn't activate the encoded filters

[jacekiwaszko1]

The filter tool should activate the filter encoded in the file, but it isn't working now.

**kern	**kern
1c	1cc
=	=
*-	*-
!!!filter-test: extract -s 1
!!!filter: filter -v test

After adding the filter -v test to the code above it should be rendered as single staff due to extract -s 1, but nothing changes:

After compiling, the HTML code with the help page is added at the beginning of the file, as if the option -v was not recognized:

!!@@BEGIN: PREHTML
!!<table>
!!   <tr>
!!      <th>Option</th><th>Type</th><th>Default</th><th>Description</th>
!!   </tr>
!!   <tr>
!!     <td>--debug</td><td>boolean </td><td>boolean </td><td> </td><td>print debug statement </td>
!!   </tr>
!!   <tr>
!!     <td>-v</td><td>string </td><td>string </td><td> </td><td>Run filters labeled with the given variant </td>
!!   </tr>
!!</table>
!!@@END: PREHTML
**kern	**kern
1c	1cc
=	=
*-	*-
!!!filter-test: extract -s 1
!!!Xfilter: filter -v test

Fixed:

I was testing how to display options for a filter above the notation (but it was not finished when I got distracted and somehow it activated with the filter filter). I have removed the code for now and things are behaving for me (and should on the POPC2 website and VHV).
