Added mockTempFileManager to tests in EML-to-PDF mockito to resolve errors (#3826)

# Description of Changes

Resolving conflict that comes from conflicts between #3797 and #3806

#3797 modified the code:
- The convertEmlToPdf and convertHtmlToPdf methods now require a
TempFileManager tempFileManager argument.
- All code (including tests) that calls these methods must now provide a
valid TempFileManager instance.

After that however, #3806 did not account for these changes,
specifically the changes to the required arguments.
