keda: Templates name aren't clear in the output in the error log for the latest e2e testing.

Report

While doing negative testing on the latest migrated code for the e2e testing, the output for a test with erroneous template was this:

cannot apply file - error: error parsing /tmp/tempTemplateFile393652011: error converting YAML to JSON: yaml: line 31: could not find expected ':'

This proves to be confusing in case we have scalers with multiple templates.

Expected Behavior

The expected behavior was something like this:

cannot apply file - error: error parsing /tmp/deploymentTemplateFile393652011: error converting YAML to JSON: yaml: line 31: could not find expected ':'

or as mentioned by @JorTurFer it could also be printing the template itself in the error log.

Actual Behavior

The error log doesn’t provide clarity to which exact template file is causing error and the error is like this:

Error Trace:	helper.go:170
        	            				helper.go:178
        	            				helper.go:209
        	            				cpu_test.go:127
        	Error:      	Received unexpected error:
        	            	error: error parsing /tmp/tempTemplateFile1287392103: error converting YAML to JSON: yaml: line 31: could not find expected ':'

Steps to Reproduce the Problem

1. make an error in templateFile.
2. Run go test on the test file with : go test -v ./scalers_go/scalerName/scalerName_test.go
3. find the error in output
