bug(#268): allow vertical-bound-method in application-duality

[h1alexbel]

In this PR I've updated application-duality lint to handle @as references in vertical and horizontal method bounds.

see #268
History:

• bug(application-duality false alarm #268): skip first
• bug(application-duality false alarm #268): count(as) not 0

@maxonfjvipon please check this one. I'm not sure if my fix is right. Would like to hear your feedback

[maxonfjvipon]

@h1alexbel let's simplify all of this with something like:

<xsl:variable name="args">
  <xsl:choose>
    <xsl:when test="starts-with(@base, '.')">
      <xsl:value-of select="o[position()&gt;1]"/>
    </xsl:when>
    <xsl:otherwise>
      <xsl:value-of select="o"/>
    </xsl:otherwise>
  </xsl:choose>
</xsl:variable>
<xsl:if test="count($args) != count($args[@as]) and count($args) != count($args[not(@as)])"/>
