Closes #13418

Fix Description

Basically the title was not being filtered before the URL for "Search ShortSience" was built. so I updated it to passing the filtered title. I am filtering the title using org.jabref.model.strings.LatexToUnicodeAdapter.
Specifically i am using the format method as it has a fallback in it to return the original text if no latex is found, so I did not have to use any if statements or the .orElse()

Steps to test

I have created the test getShortScienceSearchURLWithoutLaTeX() in ExternalLinkCreator.java

The test is basically doing the following:

1. Creating a new BibEntry
2. Setting the title which contains latex in it
3. created 2 variables (url and expectedUrl)
4. url calls the getShortScienceSearchURL() function which returns the url constructed
5. expectedUrl is basically just a string which contains the url which is required.
6. Then i just do assertEquals to check if the url and expectedUrl is the same or not.

Manual Testing (if anyone wants to)

1. add a new entry. I created a new one using the biblatex source and used the following which was provided in the issue:
   @Article{Kopp2009,
   author = {Oliver Kopp and Daniel Martin and Daniel Wutke and Frank Leymann},
   journal = {Enterprise Modelling and Information Systems},
   title = {{The Difference Between Graph-Based and Block-Structured Business Process Modelling Languages}},
   year = {2009},
   month = jun,
   number = {1},
   pages = {3--13},
   volume = {4},
   }
2. Save it
3. The click "search ShortScience" from the options. I just did right click on the entry.

4. It then leads you to the ShortScience page and the title entered is without latex
