`uses` field of `TModel` does not contain use

[toinehartman]

Describe the bug

The TModel has a list of uses and a use-def relation. Despite entries existing in the relation, the uses field is empty.

To Reproduce

import lang::rascalcore::check::Checker;

import IO;
import util::Reflective;

void main() {
    A = "
        'module A
        'int f(int i) {
        '   int x = 2;
        '   return i * x;
        '}
        'void main() { f(); }
    ";

    projLoc = |memory://tests/tmodels|;
    pcfg = pathConfig(srcs = [projLoc + "rascal"], resources = projLoc + "target");
    writeFile(pcfg.srcs[0] + "A.rsc", A);

    ccfg = rascalCompilerConfig(pcfg);
    ms = rascalTModelForNames(["A"], ccfg, dummy_compile1);
    <found, tm, ms> = getTModelForModule("A", ms);
    if (!found) throw "No TModel! <ms.messages>";

    print("tm.useDef: ");
    iprintln(tm.useDef);

    print("tm.uses: ");
    iprintln(tm.uses);
}

Running this:

rascal>main()
tm.useDef: {
  <|memory://tests/tmodels/rascal/A.rsc|(78,1,<7,14>,<7,15>),|memory://tests/tmodels/rascal/A.rsc|(12,50,<3,0>,<6,1>)>,
  <|memory://tests/tmodels/rascal/A.rsc|(53,1,<5,10>,<5,11>),|memory://tests/tmodels/rascal/A.rsc|(22,1,<3,10>,<3,11>)>,
  <|memory://tests/tmodels/rascal/A.rsc|(57,1,<5,14>,<5,15>),|memory://tests/tmodels/rascal/A.rsc|(35,1,<4,7>,<4,8>)>
}
tm.uses: []
ok

Expected behavior I would expect the list of uses to contain 3 unique Use entries.
