UX inefficiency: folder is created even if there is no content harvested

[kmmanoj]

Unlike pinned messages, if the passwords, aws-keys.txt, private-keys, urls are not found it is not acknowledged properly.
In case of specific harvesting, such as for example only credential-scan an empty folder is created inspite of no harvested data.

Steps to reproduce

• Replace CREDENTIAL_REGEX with a random value such that it does not match any message.
  CREDENTIAL_REGEX=r"lorem ipsum xyz abc mno"
  

  SlackPirate/SlackPirate.py

  Line 92 in 5014833

  CREDENTIALS_REGEX = r"(?i)(" \

  
  and replace CREDENTIALS_QUERIES with random value.
  CREDENTIALS_QUERIES = ["lorem"]
  

  SlackPirate/SlackPirate.py

  Line 38 in 5014833

  CREDENTIALS_QUERIES = ["password:", "password is", "pwd", "passwd"]

• Run $ ./SlackPirate.py --token xoxs-xxxxx --credential-scan
• Observe creation of a new folder but no passwords.txt created.

A solution that I can think of is:
Before returning the control back to the main function, a cleanup function can remove the empty files and directories created as part of the process.
