deps-by-tech: should not respect context for other entities

[blond]

If file with name block__elem.deps.js will contain:

({
    tech: 'js',
    shouldDeps: {
        block: 'other-block',
        tech: 'bemhtml'
    }
})

Actual:

exports.blocks = [{
    name: 'other-block', 
    elems: [{ name: 'elem' }]
}];

Expected:

exports.blocks = [{
    name: 'other-block'
}];

Is the same true for mod files.
