Files coverage computation error

Bug report

Looking at the my file coverage percentage and comparing it to the actual individual file coverage I believe the result does not reflect the reality. At least not my interpretation of "a file is covered".

• Empty files should be considered covered: 0 / 0 correctly gives 100% file coverage but seem to count as an uncovered file
• Non-empty zero-coverage files should be considered uncovered: 0 / N correctly gives a 0% file coverage but seems to count as a covered file

Relevant logic seems to be here:

CDash/resources/js/vue/components/BuildCoveragePage.vue

Lines 344 to 350 in 94d115a

	totalFilesCovered() {
	return this.coverage?.reduce((total, edge) => total + (edge.node.linesOfCodeTested + edge.node.linesOfCodeUntested > 0 ? 1 : 0), 0) ?? 0;
	},
	totalFilesUncovered() {
	return this.coverage?.reduce((total, edge) => total + (edge.node.linesOfCodeTested + edge.node.linesOfCodeUntested === 0 ? 1 : 0), 0) ?? 0;
	},
