Remove No scaling warning

[raphaelshirley]

Currently when a fit fails lephare throws a warning such as:

"WARNING: No scaling --> No z 193"

from:

lephare/src/lib/onesource.cpp

Line 135 in 69cc0b3

if (nf == 0) cout << "WARNING: No scaling --> No z " << spec << endl;

I think in general this may be where there is not a single band available. This is an important warning but for some real catalogues this can be true for large numbers of objects. Perhaps it would be better to condense the output to something like:

"WARNING: x objects out of y had no scaling and therefore have no redshift estimate. This is probably due to missing data"
