Xporter Licensing screen is not shown when the license is an Atlassian license

With the new version of Xporter (6.2.4) we have changed the behavior, which is why Xporter is not available, where the license placed in "Xporter - License Management" has priority over that placed in "Manage Apps".

With this improvement, it is intended that Xporter has the following behavior:

• If license valid under "Xporter - License Management" - Xporter considers this license
• If invalid license in "Xporter - License Management" - Xporter considers the license entered in "Manage Apps"

Note: In cases like this, you may want to check why the "remove" license is not behaving correctly by giving the following error:
