Asset import fails if there is a query string

[nyehughes]

Description

Asset import fails with the following error:
Invalid characters passed for attempted conversion, these have been ignored - AssetHelper.php: 321.

Googling around seems to suggest problem is trying to use base_convert($string, 10, 36) with a non-number, on PHP versions more than 7.4.

Steps to reproduce

import an asset with a query string, for example, WFOCouncil-StPetersburg.jpg?dl=1

Additional info

• Plugin version:4.2.0.1
• Craft version: 3.4.9
• PHP version: 7.4.3
