[FIX] parser: t-esc/t-out vs t-translation*

The directives t-esc/t-out both discard the ASTs that are not of DomNode
type. Since the directives t-translation and t-translation-context both
creates AST wrappers of type TTranslation and TTranslationContext
respectively, mix t-esc/t-out and t-translation/t-translation-context
does not work. For example parse

<span t-esc="'Hello'" t-translation="off"/>

gives the AST

{
    type: ASTType.TEsc,
    expr: "'Hello'",
    defaultValue: "",
}

This makes the span not been rendered in the end.

We fix that problem.
