The Upload component has the option to configure it to accept single or multiple files for upload. 

When the component is configured to accept only one file, the text in its Select button should be in singular form - "Select file..." instead of "Select files..."

Describe the bug
The current version of the Native Upload doesn't display icons for the Close/Cancel and Retry buttons that are visible in the files' list of the component.

• As a temporary workaround, the Kendo Font icons can be added to your project

To Reproduce

1. Open this example
2. The discussed icons are missing

Expected behavior
The Cancel and Retry buttons should be visible as in this screenshot:
