Inserting link fails when linkText is set to false

[tpetry]

Expected behavior.

When selecting a text inside froala, clicking the link toolbar button, typing an url and hitting save the text should be converted to an url.

Actual behavior.

A js error is thrown:

VM20 froala_editor.pkgd.min.js:7 Uncaught TypeError: Cannot read property 'value' of undefined
    at b.val (VM20 froala_editor.pkgd.min.js:7)
    at Object.E [as insertCallback] (VM20 froala_editor.pkgd.min.js:7)

    at a (VM20 froala_editor.pkgd.min.js:7)
    at HTMLButtonElement.<anonymous> (VM20 froala_editor.pkgd.min.js:7)

I have also encountered this bug in 3.0.5 on Win 10 with Firefox 69.

When linkText = false, links cannot be inserted and a javascript error appears in console.
