Error when integrating with `cache_parameters = true`

[SouthEndMusic]

Describe the bug 🐞

When integrating it seems any interpolation type which was defined with cache_parameters = true, in some cases the computation fails with an attempt to evaluate the cached integral vector at index 0.

Expected behavior

Integration without error 😋

Minimal Reproducible Example 👇

using DataInterpolations

A = LinearInterpolation([1.0, 2.0], [1.0, 2.0]; cache_parameters=true, extrapolation=ExtrapolationType.Extension)
DataInterpolations.integral(A, 0, 1.5)

Error & Stacktrace ⚠️

oundsError: attempt to access 1-element Vector{Float64} at index [0]
Stacktrace:

So it occurs when idx2 = 1 which means that no complete interval between data points is in the integration interval
