New-PoshBotFileUpload can crash poshbot

[RamblingCookieMonster]

Hiyo!

Long story short, if you try to clean up a file before it hits this, PoshBot dies and restarts.

Expected Behavior

• PoshBot doesn't crash
• I can clean up files I send

Current Behavior

• PoshBot crashes if a non-existent path is specified
• PoshBot doesn't let me delete files in the same plugin command that calls New-PoshBotFileUpload

Possible Solution

Both of these might come in handy

• Adding a Test-Path gate before Send-SlackFile, with friendly output to inform users of the error
• Adding a -CleanUp or similar parameter to New-PoshBotFileUpload to delete files after uploads

Steps to Reproduce (for bugs)

Send a nonexistent file with New-PoshBotFileUpload

Cheers!
