Get-SFImageStoreContent throws and does not honor -ErrorAction Ignore

[K-Cully]

Describe the bug
When calling Get-SFImageStoreContent, if a match is found it is returned to the caller.
If no match is found an exception is thrown, which is probably a bug in itself.
However, the exception is still thrown when -ErrorAction Ignore is passed to the cmdlet causing the calling script to exit.

To Reproduce
Create a script that connects to a cluster, then calls:
$result = Get-SFImageStoreContent -ContentPath "ContentNotThere" -ErrorAction Ignore
then continues processing in the script.

Expected behavior
The script continues executing.
