Antonio Sanchez 90187a33e1 Fix SelfAdjoingEigenSolver (#2191 )

Adjust the relaxation step to use the condition
```
abs(subdiag[i]) <= epsilon * sqrt(abs(diag[i]) + abs(diag[i+1]))
```
for setting the subdiagonal entry to zero.

Also adjust Wilkinson shift for small `e = subdiag[end-1]` -
I couldn't find a reference for the original, and it was not
consistent with the Wilkinson definition.

Fixes #2191.
