Wiki fields are being exported with additional spaces

Description

When we attempt to export wiki fields, Xporter adds unnecessary spacing and line breaks in the output document.
This issue first appeared in version 7.2.2 and persists in the current version.

However, when exporting using an older version, such as 7.2.0, the field is exported correctly.

Pre-conditions

Create a issue with a description, for example:

h1. Test

Test Text
 * Hello1
 * Hello2

h2. Next paragraph

this is an example:

→ Does your function need to be added in relevant functions?
h2. Access

Jira Access has to be discussed
|*Developer:* Testname|
|*Testing:* Testname|
|*Legal:* Testname |
|*IT:* Testname|

 

How to reproduce

1. Go to the issue
2. Select the template in the Xporter menu
3. Download the output file 

Actual result/Attachments

We can see the document has extra spacing between sentences

Expected result
The document should look the same as in Jira

Version

• 7.2.2 ~ 7.2.4-j9

Workaround
Downgrade Xporter version to 7.2.0.
