Small fix of names in reshape.test.js

Add spec for reshape() in test/function/matrix
...
This spec tests `reshape()` with more cases than the one in
test/utils/array.test.js, including various types.
Also, in `_reshape()`, throw a brand new `DimensionError` instead of
modifying the caught one (the error message does not change when other
attributes are modified, as it is computed when the error is created).
