cppu::UnoType<sal_uInt8> corresponds to UNO boolean, so its use made the
unsigned values be converted to a true/false in Any; and additionally,
using such a boolean Any, even having a 'true' value, as a parameter to
a double argument would make operator >>=(const Any &, double &) return
false, giving the resulting double equal to 0.
The wrong conversion of UShorts and ULongs to cppu::UnoType<sal_uInt8>
(aka TypeClass_BOOLEAN) was introduced in commit

#87927# Map TypeClass_BYTE to SbxINTEGER instead of SbxBYTE because of signed/unsigned problem
an attempt was made to handle obviously this same problem, changing the
corresponding UNO type to TypeClass_SHORT. But it seems that it created
problems when passing arrays of Byte through UNO to COM, where it needed
to convert to a safearray, so this decision was reverted in commit
dd6ba6b64a

mib17: #162917# let basic byte use one byte, let olebridge convert sequence to safearray correctly
This change tries to avoid the problem that caused the latter revert,
by only treating Bytes as UNO shorts in getUnoTypeForSbxValue, where
scalar Byte values are considered, keeping old handling for arrays.
