Link attributes are not displayed in the TextLinkPlugin and SimpleIconPlugin plugins

[execut]

For example, we have this text link:

Expected:

<a href="http://ya.ru/" title="titleasdasd" target="_blank" class="cms-plugin cms-plugin-5678">testt</a>

actual wrong result:

<a href="http://ya.ru/" class="cms-plugin cms-plugin-5678">testt</a>

Also SimpleIconPlugin has this bug.

I think this is similar to the previous error with another plugin #397
