`ifs_same_condition` not considering inferred types

[wawel37]

We are getting:

warn: Plugin diagnostic: Consecutive `if` with the same condition found.

for

if let Some(point_box) = sample_values_at_column.try_into() {   
   let [point_sample]: [QM31; 1] = (*point_box).unbox();
   ...                  
} else if let Some(tuple_box) = sample_values_at_column.try_into() {
   let [prev_point_sample, point_sample]: [QM31; 2] = (*tuple_box).unbox();
   ...
}

The first branch is getting the TryInto<Span<T>, @Box<[T; 1]>>, and the second one is getting TryInto<Span<T>, @Box<[T; 2]>>.

AC:

• Verify if it's expected to throw that diagnostic here.
• If not, fix it.
