id collision leading to bugs

[eugene1000x]

There seems to be collision of ids if same group (with same internal chrome group id) or same tab (with same internal chrome tab id) is added to session multiple times.

1. If same group is added to session multiple times, it is not handled properly. See groups.mp4 for poc.

Export shows that group id has been duplicated:

[
	{
		...
		"tabTree": [
			{
				"id": 1312048148,
				"title": "d",
				...
				"children": [
					{
						...
						"groupId": 1312048148,
						...
						"title": "Google",
						"url": "https://www.google.com/",
						...
					}
				]
			},
			{
				"id": 1312048148,
				"title": "c",
				...
				"children": [
					{
						...
						"groupId": 1312048148,
						...
						"title": "Google",
						"url": "https://www.google.com/",
						...
					}
				]
			},
			{
				"id": 1312048148,
				"title": "b",
				...
				"children": [
					{
						...
						"groupId": 1312048148,
						...
						"title": "Polygon PoS Chain (POL) Blockchain Explorer",
						"url": "https://polygonscan.com/",
						...
					}
				]
			},
			{
				"id": 1312048148,
				"title": "a",
				...
				"children": [
					{
						...
						"groupId": 1312048148,
						...
						"title": "Polygon PoS Chain (POL) Blockchain Explorer",
						"url": "https://polygonscan.com/",
						...
					}
				]
			}
		],
		...
	}
]

2. If same tab is added to session multiple times, there is glitch with deletion - different tab is deleted instead of intended one. See tabs.mp4 for poc.

Export shows that tab id has been duplicated:

[
	{
		...
		"tabTree": [
			{
				...
				"id": 1589573173,
				...
				"title": "Arbitrum One (ETH) Blockchain Explorer",
				"url": "https://arbiscan.io/",
				...
			},
			{
				...
				"title": "a",
				...
				"children": [
					{
						...
						"id": 1589573173,
						...
						"title": "BNB Smart Chain (BNB) Blockchain Explorer",
						"url": "https://bscscan.com/",
						...
					}
				]
			}
		],
		...
	}
]

While in other cases there are unique ids like "Qfw1VpWvOxRCk3s8". So solution might be to always use unique ids.
