Add new language pop-up shows previously added language details.

When we are adding new languages after adding 1st language, once we again click on Add new language buttons it shows previously added language details.

Steps to Reproduce:

• Go to the zanata home.

• Click on Languages menu from left panel.

• Click on "+ Add new language".

• Add any of the language.

• Click on save button.

• Again click on" + Add new language"

• Observe the pop-up.

• Close that pop-up and again click on "+ Add new language"

• Observe the pop-up.

Actual Result:

• Previously added language details shown on add language pop-up while adding second language.
  -Those details shows only first time.

• If we close that pop-up and again click on add new then it shows pop-up with cleared details.

• If we refresh the page after adding first language and click on add new its shows cleared pop-up.

Expected:

• The add new language pop-up should have to be cleared at every time while adding new language.

• Dosen't need to do manually refresh of page after adding new language.
