What is the current behavior?

A small typo during a refactor (#2710) caused the checkRun graphQL query to be run with a commit depth of 0 when no commit depth is specified, so the query returned no data. This was causing more SAST checks to be cache misses.

go run main.go --repo ossf/scorecard --checks SAST --format json
INFO[0023] listCheckRunsForRef cache miss: ossf/scorecard:476a246ebbafa7f8785505621010f76123bd5059 
INFO[0024] listCheckRunsForRef cache miss: ossf/scorecard:f26282c2f3b3bcc099c1167cf62a87cfd79afbf8 
INFO[0024] listCheckRunsForRef cache miss: ossf/scorecard:227bb4a7df92eb217670c46893ac25cb19dbed25

... etc

What is the new behavior (if this is a feature change)?**

The proper value is passed to the checkrun handler, so the graphQL query populates data and there are fewer cache misses.
