Stop unnecessary quote escaping on vue v-bind strings

[DavidSemke]

This PR solves issue #531. Previously, using the Vue v-bind directive on an attribute whose value involved a string could result in the string's delimiting quotes being incorrectly escaped. Now escaping behaves as expected, so this:

div(:value=attributes['data-value'])
div(:value=attributes['"data-value"'])
div(:value=attributes['"\'data-value\'"'])
div(:value='"\'data-value\'"')

Becomes this when formatted:

div(:value=attributes["data-value"])
div(:value=attributes['"data-value"'])
div(:value=attributes["\"'data-value'\""])
div(:value="\"\'data-value\'\"")

Some quotes are transformed because of option singleQuote or pugSingleQuote being set to false.
