Prefix ids plugin don't add prefix if prefix is false

[vzaidman]

i use it like this:

plugins: [
          {convertPathData: false},
          {prefixIds: {
            prefix: node => {
              const elementName = node && node.elem
              if(!elementName || elementName === 'svg' || elementName === 'use'){
                return false
              }

              return 'some-prefix'
            }
          }}
        ]

and i expect no prefix when i return prefix as false.

it can also be used as

plugins: [
          {convertPathData: false},
          {prefixIds: {prefix: false}}
        ]
