fix(parser): use element name parser to extract name for raw parser

In the existing code, if the raw element name is successfully parsed,
it immediately attempts to parse the attributes, without checking
for whitespace or a closing `>`.

This means that something like `<scripts>` would be parsed as a
`<script>` tag with a boolean attribute of `s` (the last character of
the tag name). This would then give a confusing error about mismatched
tags as the closing `</scripts>` tag was actually parsed correctly.

This commit fixes this issue by delegating to the elementNameParser,
which checks for whitespace or a closing `>`, and then compares the
names of the elements.
