AnalyzeTemplate should not throw an exception on recursive templates

[chrimc62]

Versions

Package: 4.13.6
Node: 12.19.1

Describe the bug

When analyzing this template a recursive loop exception is raised.

# sortNumber(number, divisor)
> Return a string with leading zeros out to divisor
- ${if(divisor == 1,
    string(number),
    concat(string(div(number, divisor)), sortNumber(mod(number, divisor), div(divisor, 10))))}

Expected behavior

sortNumber should list itself as one of the templates it uses and there should be no exception.

@Danieladu, git blame shows you are someone that's pretty familiar with this code. Could you take a look?

@chrimc62 You have created the same issue before: #3619, and we fixed it in #3621 two months ago. But the change would appears in 4.14 version.
Could you take a look and make sure it meets your requirements.

I've added a test case via the linked PR, but I'll close this issue as it does not reproduce in main.
