ng i18n --ivy, incorrect value in "equiv-text"

[Niklas187]

🐞 Bug report

Command (mark with an x)

• new
• build
• serve
• test
• e2e
• generate
• add
• update
• lint
• xi18n
• run
• config
• help
• version
• doc

Is this a regression?

not really, but it works correct without the new "--ivy" flag

Description

If you do have a i18n translation with an interpolation and then run "ng xi18n --ivy" the generated xlf file does not have the correct value in the "equiv-text" attribute.

Example:
<x id="INTERPOLATION" equiv-text="&quot;\uFFFD0\uFFFD&quot;"/>

🔬 Minimal Reproduction

1. git clone https://github.com/Niklas187/ng-xi18n-ivy-bug.git
2. npm i
3. npm run ex

🔥 Exception or Error

In the xlf file i would expect:
<x id="INTERPOLATION" equiv-text="{{interpolationValue}}}"/>
