Exclude URLs that already overlap with defaults (on first launch too)

[fregante]

Extension of:

• Exclude URLs that already overlap with defaults #12

The above issue was fixed with:

webext-dynamic-content-scripts/index.ts

Line 56 in 1816d8a

excludeMatches: config.matches,

But it didn't cover injectToExistingTabs:

webext-dynamic-content-scripts/index.ts

Lines 27 to 32 in 1816d8a

	chrome.tabs.query({
	url: origins,
	}, tabs => {
	for (const tab of tabs) {
	if (tab.id) {
	void injectContentScript(tab.id, scripts);

This is particularly visible when all_urls is granted, so it always covers all tabs.
